Abstract

La présente invention concerne un procédé d'activation et de configuration de partie de bande passante (BWP), un dispositif terminal, une puce, un support de stockage lisible par ordinateur, un produit de programme informatique et un programme informatique, conçus de telle sorte qu'un côté terminal peut prendre en charge l'activation simultanée d'au moins deux BWP. Le procédé comprend les étapes consistant à : dans un premier ensemble de ressources de commande configuré sur une première partie de bande passante (BWP) et un premier espace de recherche, détecter une instruction d'activation pour au moins une seconde BWP, la première BWP étant dans un état activé et ladite seconde BWP étant dans un état désactivé ; et lorsqu'une instruction d'activation pour au moins une seconde BWP est détectée, activer ladite seconde BWP.
